1 Claim.

This invention relates to paving strips commonly employed between thepaving slabs or blocks of a street, and between such slabs or blocks andthe curbing. The general object of the 6 invention is to provide astrong durable paving strip, of economical construction, which permitsfree expansion and contraction of the paving proper without danger ofdistortion or fracture of the strip. Another object of the invention isto provide a water-proof strip which can be conveniently handled andshipped, and is capable of effecting a permanent adhesive union withcement or other paving slabs or blocks.

In the accompanying drawing wherein a preferred embodiment of theinvention is illustrated:

Figure 1 is a perspective view, partly in section and partly brokenaway, of a pavement showing the improved strip; and v Figure 2 is anenlarged fragmentary view of the pavement partly broken away to" showthe construction of the strip.

Referring more particularly to the drawing 1 denotes a street pavementcomprising curbing 2 and blocks or slabs 3 preferably of cement, whichcurbing it will be understood extends along both sides of the street orroad 4. The slabs or blocks 3 suitably arranged between the curbs, maybe of any desired size and shape, but are preferably rectangular, asshown. The improved paving strip consists of a relatively thin and flatbody portion 6 of elastic and flexible material such as petroleumresiduum, of asphaltic rubber-like texture and consistency. As the body6 of the strip is identical with that of the paving strip illustrated inmy prior Patent No. 1,134,939, granted April 6, 1915, furtherdescription is deemed unnecessary.

The strips are molded into any desired length for insertion betweenadjacent paving slabs or between said slabs and the curbing and securedto each side face is a covering member I consisting of two plys orsheets 8 of thin tough paper, coated upon their inner superposed faceswith a layer of waterproof adhesive material 9. A layer ill of suitablyarranged vegetable fibre interposed between the sheets 8 and embedded inthe adhesive 9, reinforces the strips and in co-operation with papersheets 8 provides a suitable covering. As the outer faces of the paperplys 8 are smooth and non-adhesive the strips can be readily shipped andhandled and packed one upon the other for a reasonable length of timewithout sticking. However, the water proof adhesive 9, which is of tarlike consistency impregnates the plys 8 sufficiently to render themwaterproof.

After the strips have been inserted between the concrete slabs 3 orbetween the slabs and the curbing, the strips soon form an adhesiveunion with the concrete, and being substantially nonresilient would beliable to rupture under abnormal expansion and contraction of thepavement if fixed to each other against relative movement. This dangeris obviated however, due to the fact that the adhesive 9 is sufficientlygummy to permit of slight relative sliding movement between the plys ofeach covering member 1.

It has one to the other.

Having thus described my invention, what I claim is:

A paving strip adapted to seal the space between adjacent sections of astreet paving comprising a body member of flexible material, a pair ofcovering members affixed to opposite sides thereof, said coveringmembers each including superposed sheets of tough paper adhesivelysecured together, said sheets being capable of relative sliding movementwith respect to each other under expansion and contraction movements ofsaid pavement, and reinforcing means between said sheets.
